3 On Sign Language Sign languages create representations in the space in front of the signer (Signing Space) Due to the importance of vision, signed languages take advantage of spatial representations (he, she, it, etc.) The linguistic uniqueness of sign localisation is beyond doubt 070911 3 Bhattacharya/ USOF/ DOT

4 The Signing Space 070911 4 Bhattacharya/ USOF/ DOT

5 Time in Indian Sign Language: An Example 070911 5 Bhattacharya/ USOF/ DOT

6 SL Technology Text/ Speech-to-Sign  Voice recognition module (Speech Recogniser)  Conversion of sentence to fit the grammar of sign language (Inter-Language Translator)  3D Avatar Animation Module Sign-to-Text/ Speech  Sign Recognition: Video Signal input to large vocabulary speech recognition database  Automatic machine translation system to create a spoken language translation Problems : Simultaneousness; 3D body-centred Signing Space; Sub-word units 070911 6 Bhattacharya/ USOF/ DOT

7 Status of SL Recognition Systems 070911 Bhattacharya/ USOF/ DOT 7 “ Today’s Sign Language recognition is at about the stage where speech recognition was 20 years ago ” -- Thad Starner, Head of the Contextual Computing Group at the Georgia Institute of Technology

8 Challenges to ICT for Deaf 070911 Bhattacharya/ USOF/ DOT 8 The major barrier in using ICT for the Deaf is the assumption that English/ Hindi/ State language is their first language – their capabilities are often measured against understanding the written word Most effective ICT for the Deaf is visual rather than based on the written word or sound Text messages are limiting since it doesn’t convey emotions, voice inflections or body language (similarly Text-Speech systems) The smart phones with front-facing cameras for videoconferencing can be used for video chat but are too much of a bandwidth hog

9 Applications Currently Available or Under Research 070911 Bhattacharya/ USOF/ DOT 9 Video Chat Softwares Online Dictionaries Speech-Signal Translators Automated SL Generation System Smart Phone Applications

15 Existing Infrastructure 070911 Bhattacharya/ USOF/ DOT 15 Schools, Common Service Centres, Primary Health Centres, Panchayats, Women’s Self Help Groups (SHGs), already covered under various USOF programmes Rural and Remote Areas Mobile Services of USOF: 500 districts in 27 states Rural Broadband Scheme: 8,61,459 Broadband connections; Scheme for Intra- District Networks on Bandwith Sharing with 2.5 Gb capacity

16 Future Directions 070911 Bhattacharya/ USOF/ DOT 16 Development of the ISL sign set Development of software for converting Hindi/ regional language words to ISL through online dictionary Interactive learning software using the NBT book series for shapes, measures, colours, time, money for 2-3 year olds; newspaper and adult education for Deaf adults Send video over both 3G and Wi-Fi networks at a very low bit rate Optimisation of compressed video signals by increasing image quality around the face and hands to bring data rate down Motion detection to identify whether a person is signing or not for extending battery life
